You should be able to latch on to it with a pair of needle nose pliers and yank it out. It has a couple of o-rings on it, so it may take a tug or two. There are a few instances where the o-tube is an integral part of the hose its in, but if you already have a replacement tube, you would be able to tell if that's the case or not.
Thanks for the input. I have tried the needle nose pliers but could not get it out. I will keep trying. I have the new one and it looks like it should just slip out.
